SPECIFICATION forming part of Letters Patent No.' -330,677, dated November 17, 1885. Application filed March l0, 1885. Serial'No. 158,34. (No model.)

To all whom it may concern.' I

Be it known that I, GEORGE OARROTHEES, a citizen ofthe United States, residing at Piedmont, in the county of Harrison and State of Ohio, have invented certain new and useful Improvements in Cultivators; and I do declare the following to be afull, clear, and eXajct description of the invention, such as will enable others skilled in the art to which it appertains The invention aims to provide and arrangeA two springs in such manner relatively to each other, and to the framing and the drag-bar, that said springs will operate to hold the dragbarin the ground or up clear of the ground in such adjustments of the drag bar as will be hereinafter described.

The invention further consists in so supporting and arranging the drag-bar support and the crank-bearing collar, that such parts may be adjusted and set at different angles relatively to each other for the purposes hereinafter set forth.

The invention further consists in so forming and connecting the several parts that when one part becomes broken or worn out it may be readily replaced without involving the purchase of a new implement; and the invention further consists in other improvements which will be hereinafter fully described, and more specifically pointed out in the claims.

In the drawings, Figure l is a side view, with one of the wheels broken away, of a cultivator constructed according to my invention. Fig. 2, an enlarged detail side view of the construction in the region of the spindle, the wheel being removed. Fig. 3 is a plan View of a portion of the construction shown in Fig. 2. Fig. 4 is a detail side View of the intermediate collar. Fig. 5 represents the dragbar coupling in detail. Figs. 6 and 7 are respectively detail views of the crank -bearing collar and the sleeve.

.desired construction.

The framing Aand spindle B may be of any On the framing A are supported guides or eyes a a', arranged on the 'opposite side of a vertical line drawn through the spindle. On this spindle I journal a sleeve, C C. This spindle-sleeve is formed exteriorly hexagonal in cross-section, and is made of a length sufcient to receive the crank-bearing collar `D and the drag bar coupling E. The 4collar D is fitted at d, to be slipped over the sleeve C, and has its lower end split at d', forming the lugs d2 d2, to receive the bolt by which the collar is secured removably on the sleeve. This collar is provided-at its upper end with cranks F F', arranged one in advance of the other, as shown.l To these cranks I secure rods G G', the upper or free ends of which rods are'projected through the guides a a', as shown in Figs. 1 and 2.; Springs II H are placed on the rodsG G and bear between the .cranks F F and the guides a a. The dragbar coupling is formed at -e to t over the sleeve O, and is slit at e', forming the lugs e, to receive the bolt by which said bar is clamped in position. Obviously this coupling might be an integral part of the drag-bar. I prefer to form it separately, as shown, and to connect the said drag-bar with it in the manner presently described. To this end I provide the coupling E at its rear end with arms E Ff, arranged vertically one above the other. Between these arms E E2, I journal the head I of a casting, I, so that the said casting and the drag-bar attached thereto may swing laterally, as desired. This casting I has grooves t', formed longitudinally in its opposite sides, in which to fit the ends of the drag-bars J, as will be understood from Figs. l and 2, in connection with Fig. 5. The drag-bars have their ends seated in these grooves i, and are bolted fast, said grooves serving to relieve the fasteningbolts of all vertical strain by the drag-bars engaging the upper and lower walls of said grooves. The drag-bars may have their rear end bent down to form the standards on which are secured the shoe and the mechanism for supporting said shoe, so -they may yield to pass obstructions. This latter construction, however,

forms the subj ect-matter of another application for patent of even date herewith, and need not consequently be described in this specification,

IOO

In operation, when the parts arein the position shown in Figs. vland 2,springs H Hpperate equally to hold the said parts in such position. If, however, the parts are elevated, as shown in dotted lines, Fig. 2, the springs, as also indi cated, will be thrown forward at their` lower ends and will operate inaconsiderable degree l to hold the drag-bar in an elevated position. When the drag-bar is depressed below the full line position shown,the springs will have their lower ends thrown in rear of the vertical, and will operate to hold the said guide-bar down, thus relieving the operator of considerable labor both in holding the drag-bar inan'd out of the ground. Y Y

By 'the springs arranged as shown, when the drag-bar is raised and lowered 'one of s-u'ch springs is compressed,and consequently exerts astronger force von its crank. This will be 'seen to be the case of the spring H when the 'dragbar is raised and the spr-ing H when the drag'- bar is lowered. l

By 4clamping the drag-bar coupling and the crank-bearing lcollar removably on the sleeve, Said parts may be removed from the sleeve and' adjusted rotarily to Vdifferent relative angles, setting the 'cranks of the collar nearer tofor farther from the drag-bar coupling, so that the springsmay be caused to operate more forcibly when the drag-bar is into or out of the ground. This adjustment maybe secured by 4making the sleeve round and fitting the drag-bar coupling i and the collar thereon so they 'may be 'turned on and clamped at any desired position to the collar; but I prefer t'ofor'm the collarh'exago'nal, or otherwise many sided, as by such constru'ction the parts Ina-y be clamped more `firmly thereto.

The wheel K is supported on the outer end of the spindle B. Between this wheel andthe sleeve C, I clamp a collar, L, on the spindle. This collar serves to separate the wheel from the sleeve C, -andlreceivesthe Wear of both such collars and prevents their binding oue 'against the other.

When vthe spindle is formed in the lower` end of the pendent arm B, I prefer to brace said spindle byea rod, Lf, connected at one end with a clamp, L, and at its other end with the framing A. It will be noticed that whenever any of the .parts C, D, E, I, or L become worn or broken they may be readily replaced by new ones fitted onto or within the remaining parts.

Having thus described "my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination ofthe drag-bar coupling,

guides arranged 'above and en opposite sides o-f a vertical line ldrawn through the 'axis 'o'fsa'id cou pli n'g,the 'crank-bemin g collar, rods secured at one end 'to said collar `on `opposite sides of the vertical line and extended upward ea'ch through its respective guide, Vand springs placed one on each of fsaid rods jan'd bearing between the coupling andthe 'gui-des, substam tially as set forth. l ,l

2. The combination b'fthespindie, the guides a a', arranged faboveand on yopposite sides 'of a vertical linejdrawn through such spindle, the sleeve G, fitted 'on 'the spindle, the 'collar D, clamped on the "slee'v'e C and provided with cranks F and F', the rods GG, pivbtally connect'ed Vat one end with the cranks F F and having their other ends extended, respectively, through guides a a', 'and springs placed on rods G G', and bearing between parts ,F G and F G', substantially as set forth.

In 'testimony whereof I aix my vsignature in presence of t'wo witnesses.

GEORGE CARROTHERS.
